The amazing video below uses this temporal aliasing to make water appear to do crazy things. By connecting a hose to a speaker, it can be wiggled at a speed that matches up with the speed of the frames of the video. This effectively freezes the water in mid vibration at the same point each frame. If you were on location, you would see the water spraying out in fan shape away from the end of the hose, not what we see on the video. Since the video is in phase with the vibrations, the water appears frozen in mid stream (literally), and the effect is really cool. Of course as they speed up and slow down the vibrations, the water appears to move up or down accordingly. What fun!

Temporal aliasing and bendy water - nice!
